✦Horn of Blasting

You can take a Magic action to blow the horn, which emits a thunderous blast in a 30-foot Cone [Area of Effect] that is audible out to 600 feet. Each creature in the Cone [Area of Effect] makes a DC 15 Constitution saving throw. On a failed save, a creature takes 5d8 Thunder damage and has the Deafened condition for 1 minute. On a successful save, a creature takes half as much damage only. Glass or crystal objects in the Cone [Area of Effect] that aren't being worn or carried take 10d8 Thunder damage.

Each use of the horn's magic has a 20% chance of causing the horn to explode. The explosion deals 10d6 Force damage to the user and destroys the horn.
